SPECIFICATION forming part of Letters Patent No. 779,085, dated January 3, 1905.

Application filed August 25, 1904. Serial No. 222,058.

To all whom it may concern:

Be it known that I, PATRICK KENEHAN, a subject of the King of Great Britain, residing in the city and district of Montreal, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Dumping-WVagons; and 1 do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in metallic dumping-wagons; and it consists in certain features of novelty in the detail construction and arrangement thereof whereby a dumping-wagon is produced wherein the greater portion of the framing therefor and the wagon-body supported by such framingis produced from commercial steel, which may be readily obtained in the open market.

The object of the invention is to produce a spring-supported clumping-wagon of metal which will be supported by a bolster placed intermediate the supporting-axles, the body portion being rockable upon such supportingbolster independently of the bed-frame used for supporting thebody.

Referring to .the annexed drawings, in which similar numerals of reference indicate corresponding parts, Figure 1 is a side elevational view of a dumping-wagon of the character described without its supporting-wheels.

Fig. 2 is a transverse sectional view of Fig. 1 on line 2 2. Fig. 3 is a similar view on line 3 3 looking in the direction indicated by the arrow. Fig. 4 is a detached detail of the combined body brace and clip used for connecting the tilting body upon the supporting-bolster. Fig. 5 is a fragmentary detail illustrating the manner of connecting the rear supportingsprings with the bed-frame. Fig. 6 is a section on line 6 6 of Fig. 5. Fig. 7 is an enlarged broken detail view showing the manner of supporting the rear springs upon the crank-axle. Fig. 8 is an enlarged detail view of the lifting-screw in mesh with a rockable stud adapted to be connected with the body portion of the wagon. Fig. 9 is a detail View illustrating the manner of connecting the Referring to the parts, 1 is the front axle, I

provided with the springs 2, which are connected to such axle by the clips 3 and support the platform 4:, upon which is mounted the two elements 5 of the fifth-wheel, so called. Above the fifth-wheel is a bolster 6, above which-extends transverse truck-bolsters 7 for supporting the bed-frame. This bed-frame comprises an approximately U- shaped structure consisting of the side sills 8, having the horizontal outwardly-extending flanges 9, and end sill 10, composed of a commercially-rolled angle like the side sill, but with the horizontal flange 11 projected inwardly and rearwardly, so as to serve as a convenient supporting means for the frontend portion of the wagon-body 12, which wagon-body comprises the bottom plate 13, the side plates 14:, and end plate 15, while a releasable door 16 is provided at the rear end of such body, so that when the wagon-body is tilted to the position shown in dotted lines in Fig. 1 such end plate may be opened for the purpose of discharging the contents of the wagon-body. As will be noted in Fig. 10, the end sill has its vertical and horizontal flanges split near the ends of such end sill, and the portion 10 ofsuch end sill is left longer than the portion 11 thereof, so that the said flange 10 may overlap the vertical flange of the side sill and be connected therewith by suitable rivets 17, as shown, whereby the end sill is supported in position by the side sill. The rear spring 18 is connected with the side sills by means of brackets 19, within which the front ends of such rear springs 18 are pivotally supported upon the the pintles 20, as shown in Fig. 1. The rear ends of the springs 18 are connected with the slidable plate 21, which is connected, by means of the clips 22, with the horizontal flange 9 of the side sill, so that such plate 21 is slidably mounted upon the said sill to permit more or less vibratory movement of the rear springs.

IOC

The intermediate portion of the rear springs are connected, as shown in Fig. 7 by means of the clips 23, with the upper horizontallyprojecting crank portion 24 of the rear axle 25. Extending forwardly of the brackets 19 are straps 26, which form clip 27, which serve as bearings for the circular portion 28 of the transverselyextending bolster 29, which bolster is connected by such clips 27 to and is thereby supported from the side sills before referred to.

For the purpose of locking the body 12 upon its supporting-bolster 29 clips 30, which form side braces for the body, extend downwardly, as shown in Figs. 2 and 4, and are connected by means of the plate 31 and screw-threaded portions 32 upon said transversely-extending bolster 29, a rivet-opening 33 being provided in such member 30, through which the rivet 34, connecting the side and bottom plates of the wagon-body, is projected. Connected with the upper portion of the member 30 and extending approximately to theouter end of the bolster 29 is a brace 35, while an intermediate brace 36 serves as a strengthening means therefor for uniting the body of such supporting-bolster. Intermediate the end sill and such supporting-bolster there are connected with the side walls 14 of the body clips 37, in which are rockably mounted the studs 38, which studs are provided with the trunnions 39 and are internally screw-threaded, as shown in Fig. 8. If desired, the upper portion 40 of the studs 38 may be externally screw-threaded and asleeve 41 secured thereupon, as shown in the fragmentary detail, Fig. 8. Connected with the side sills are brackets 42, within which are mounted the transversely-extending shaft 43, carrying bevelgears 44 near opposite ends thereof, with which bevel-gears mesh other gears, 45,which are looked upon the lower end of the screwthreaded rod 46, a non-circular portion 47 being provided upon the shaft 43, upon which may be mounted the crank 48 for rotating said shaft. To support the lower end of the rod 46, the bracket 49 is rockably mounted upon the shaft 43 and has bearings 50 and 51 therein provided, respectively, for the shaft 43 and the lower end of the rod46, while said bevel-gear 45 is mounted within the approximately elliptical opening 52 in said bracket 49. As the bracket 49 is rockably mounted upon the shaft 43 and the screw-threaded stud 38 is also rockably mounted within its supporting-clips 37, it is evident that when the body is being tilted the pinion 45 will ride circumferentially of the pinion 44, so that the rod 46 may occupy the position shown in dotted lines in Fig. 1, thus avoiding destruction of said rod during the tilting of the wagonbody, at which time the rear-end portion of the wagon-body will descend within the crank portion of the rear axle, which is bent downwardly for the purpose of permitting such descent. I

The operation of my improved wagon is as follows: The body being supported as shown in full lines in Fig. 1 and filled when it is desired to dump the contents thereof, all that is necessary is to apply the crank 48 to rotate the shaft 43, whereupon, through the gears 44 and 45, a screw-threaded rod 46 will be rotated in engagement with the stud 38, which is fixed to the wagon-body, thereby raising the front end of the wagon-body from its position of rest upon the flange 11 and bolster 29 to the position shown. in dotted lines in Fig. 1, in which position the weight is carried by the bolster 29, which, as will be noted, is substantially midway between the front and rear end of the side sills, and such bolster will rock in its bearings supported from the side sills during the tilting of the wagon-body.

.While I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myself to the precise form shown, for many of the details may be changed in form or position without affecting the operativeness or utility of my invention, and I therefore reserve the right to make all such modifications as are included within the scope of the following claims or of mechanical equivalents to the structures set forth.
